Core Text - NSAttributedString line height done right?

Question

I\'m completely in the dark with Core Text\'s line spacing. I\'m using NSAttributedString and I specify the following attributes on it: - kCTFontAttributeName - kCTParagraph

Answer 1

Another way of twerking with a NSAttributedString line position is playing with baselineOffset attribute:

let contentText = NSMutableAttributedString(
string: "I see\nI'd think it`d be both a notification and a\nplace to see past announcements\nLike a one way chat.")

contentText.addAttribute(.baselineOffset, value: 10, range: NSRange(location: 0, length: 5))
contentText.addAttribute(.baselineOffset, value: -10, range: NSRange(location: 85, length: 20))

Result:

"I see

I'd think it`d be both a notification and a
place to see past announcements

Like a one way chat."
